Itis my manner permit the delivery, by gravitation,

the flap extended 7 than purpose to in this the magazine, but

it is also necessary to provide means for holding upthe remainingarticles in the Therefore I provide a follower, in the form of a bail13, having arms 1.4: 1 1, by which it is attached to flanges 15, 15 of Vthe plate 10; said bail, which liesnormally just in advance of thelowermost article 9, serving to press 1 said article rearwardly, awayfrom the stack, while the member 10 whereby said bail to drop.

It will be appreciated that in the return movement of member 10 the topedge thereof again raises the flap 8 to its horizontal, stack supportingposition, and at the same time the bail 13 moves forwardly toits normalposition in readiness for a succeeding delivery operation.

As actuating means for the member 10 I have shown a yoke 16 engaging theflanges l5, and a push rod 17 extended from said yoke through the casingwall 3, spring means as indicated at 18 connecting the yoke and wall 3to provide the tension under which the member 10 is retractable to andheld against suitable stop means, in its normal, stack supportingposition.

A curved delivery chute 19, extended outwardly through an opening inwall 3, may have its inner end 20 located in a position beneath themagazine where it will serve as a stop to limit the forward movement ofmember 10. Also, as here shown the stroke of the push rod or plunger 17is limited by its head 21 coming in contact with wall 3, therebyconstituting a stop that determines the extent of the rearward movementper mitted member 10 in the article releasing and delivering operation.

It must be understood that the actuating means herein described, as wellas the respective stop means for the flap control member are given byway of example only, and that all variations within the scope and spiritof my invention are equally comprehended by the foregoing disclosure. 1

I claim:

1. The combination with a magazine to contain a stack of articles, of amovable base support for the stack, shiftable means for releasablyholding said base support in its operative position, and other meanscarried by said shiftable means, for supporting the stack when the basesupport is released to permit delivery of the bottom article.

2. The combination with a vertically disposed magazine adapted tocontain a stack of articles, of a movable, stack supporting base forsaid magazine, shiftable means to releasably hold said base in its stacksupporting position, and means carried by said shiftable means todisplace the bottom article and support the remaining stack while saidshittable means releases the base and thereby permits delivery bygravitation of said displaced article.

3. The combination with a vertically disposed magazine adapted tocontain a stack of articles, of a pivotal flap, shiftable means toreleasably hold said flap extended beneath said magazine as a stacksupport, and means, carried by said shiftable means, to displace thebottom article and move into a stack supporting position beneath thenext succeeding article.

4. The combination with a magazine to contain a stack of articles, of aflap having pivotal engagement at a point outside the gravitational pathfrom the magazine, whereby said flap is movable to and from the magazineexit as a releasable support for the stack, a vertically disposedpivotal member engaging said flap and movable through a limited arc tohold said flap in its stack supporting position and release ittherefrom, and a bail carried by said member, in rearwardly spacedrelation thereto to shift the bottom article from the stack in the flapreleasing movement of said member, whereby said bail passes into aposition beneath the stack, to support it upon the release of the flapand the consequent delivery of the shifted article.

Executed this 19th day of October, 1925.
